Well I just squealed a bit. A Tumblr user [ashesoferebor] walked past the set of Shadowhunters and took a few snaps.
The set is of the NYPD where Luke Garroway will work in the TV show.
FYI these are kind of spoiler-y so please don’t look closely if you are staying away from spoilers.
Shadowhunters is set for release early 2016 in U.S. and Canada. We are currently unsure about the rest of the world.
